Abstract

See full text

An ion beam is generated and the energy of this ion beam is changed from a first energy to a second energy through, for example, acceleration or deceleration. A portion of the ion beam is blocked after the energy is changed and the ion beam is implanted into a workpiece. A plurality of blockers may be used to block the beam. Each blocker may be attached to a drive unit configured to translate one of the blockers in a first direction.
